Discrete Element Modeling

DEM (discrete element method) is a numerical technique that models the interaction between individual particles and boundaries to predict bulk solids behavior.  This tool can easily model moving boundaries and is used to gain better understanding of particle flow dynamics.  The knowledge is then applied to design more efficient equipment, thus improving process efficiency and product quality.

DEM is used to predict:

  • Bulk material flow patterns
  • Bulk material flow rates
  • Force, torque, and power consumption of equipment
  • Impact forces on particles and boundary surface
  • Wear patterns on boundary surface
  • Velocity profiles and dead zones
  • Particle distribution in segregation and blending

Education & Training

The field of bulk material handling is quite complex.  Bulk solids theory has unique terminology, scientific flow principles that are not applicable to fluid or gas flow behaviors, and often has not been taught to engineers at the university level. Personnel responsible for designing, fabricating, installing, and operating bulk material handling equipment are often ill-prepared for the complex flow behavior occurring with bulk solids.  Thus, equipment is often designed based on a costly trial-and-error approach.

In today’s competitive global manufacturing environment, companies cannot afford this practice.  As a result, engineers, scientists, managers, and plant operators, turn to Jenike & Johanson’s world-renowned education & training on effective bulk material handling and pneumatic conveying principles.  Proper training is essential for operating an efficient and reliable bulk solids handling system.  Training helps to foster greater awareness of plant operating efficiency, safety, and process improvement.

The folks at J&J always present themselves with the utmost professionalism and expertise. I’ve worked with a some so-called ”experienced” engineering firms over the years that make a lot of conclusions with little data or analysis to back it up.

The work J&J conducted provided us with guidance on our powder system and improvements to our system have been implemented.

I would like to thank you for putting on one of the most enlightening and informative classes that I have seen in my 25 years in the polymer industry.  It had an excellent balance of theory and practical application and was applicable to many applications beyond purge columns.  I got a lot of positive feedback from the attendees.
